$$C_V$$ and $$C_P$$ denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then

$$C_P-C_V$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas.

$$C_P+C_V$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas.

$$C_P/C_V$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas.

$$C_P~.C_V$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas.
